Syracuse, N.Y. -- Syracuse police patrolling the city streets early Sunday said they found a "very large crowd" gathered in the area of Fabius and Oswego streets, and then heard shots fired.

As the crowd dispersed, more shots were fired around 12:40 a.m. Sunday in the 700 block of Oswego Street. That's when police found a 20-year-old man shot in the right ankle, Syracuse police Sgt. Thomas Connellan said in a news release.

Tyshawn Keene, 20, of Syracuse, was taken to Upstate University Hospital in Syracuse, where he is being treated for non-life-threatening injuries, the release said.

Syracuse police officers said they were unable to determine who was firing the shots or who shot Keene due to the size of the crowd, Connellan said in the release. Anyone with information about the shooting can call Syracuse police at (315) 442-5222.
